This Nicna AF Confirm Lens Mount Adapter will allow you to use Nikon Lens on Canon cameras body. This AF Confirm Lens Adapter is useful for manual focusing. With the incorporated AF-Confirmation chip set, you don’t need to guess the correct focus by naked eye, as it will be indicated by the accurate auto-focus system of EOS camera with a beep sound (just like using EF lens in manual focus mode).
Using this adapter minolta to canon, most functions such as automatic diaphragm, auto-focusing, or other functions will not operate .
In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You can shoot with manual mode or aperture priority mode.
It works pretty well on my Canon 40D and to all Nikkor G lens only.
